COLONOSCOPY
A colonoscopy is a common procedure that can help to detect any abnormal changes within the rectum and large colon. During the procedure, a long and flexible tube known as a colonoscope, is inserted into the rectum. The tip of the tube contains a tiny camera that gives the doctor a clear view of the inside of the colon.
For many patients the procedure is painless, though you may experience slight discomfort.
WHY WOULD YOU NEED IT?
Patients can be referred for a colonoscopy for a variety of reasons. These include:
- Long-term changes in your bowel habits
- Constipation
- Diarrhoea
- Itchy anus
- Anal discharge or bleeding
The procedure can help to investigate these symptoms, as well as screen for colon cancer, and remove polyps. Patients aged 50 and over with no other risk factors, will typically undergo a colonoscopy every 10 years to screen for bowel cancer.
